#12 of 20 Re: Check engine light (and other problems) [akirby] by buckeye68 Aug 19, 2009 (7:41 am)
Replying to: akirby (Aug 19, 2009 7:35 am) I did and it read the #4 engine coil was bad. I replaced it along with all the spark plugs and the gasket. The only problem is, I couldn't find the layout for a V6 only a V8 and I am wondering if I changed the wrong coil. Do you know where I can get a layout for a V^?   Thanks, buckeye68 Replies to this message: akirby (Aug 19, 2009 7:49 am) brucelinc (Aug 19, 2009 7:58 am)

Replying to: buckeye68 (Aug 19, 2009 7:41 am) No, but it's the same as the other Ford 3.0L Duratec engines (Taurus, Fusion, etc.) so it shouldn't be hard to find.

#15 of 20 Plugs/Cat Conv. by pricanpride84 Aug 26, 2009 (4:22 pm)
In June the check engine came on and began to blink as well. Took it to the dealership in July and following came back #2, #6 coils failed, Cat #1, Cat #2 banked. Dealership wanted $3400 estimated. I asked if under warranty, no luck 76200 at time. However I just made some research that my cats may be covered under the Federal Emissions Warranty act as long as my car is under 80,000. Now, if I do the coils myself, and go to a different dealer or same dealer (considering they straight out lied to me, since they are salesmen anyways); can the cats be covered due to failure of 2 coils going back, since I didn't cause the coils to fail due to mistreatment.   P.S. I do take my car for routine oil changes (high milage), change my air filter every 6 to 8 months depending how dirty and check all fluids. Also heard coils fail a lot in LS due to gaskets failures since water or oil seeps in and shorts the coil (manufacturing problem). Replies to this message: akirby (Aug 27, 2009 4:29 am)

Replying to: pricanpride84 (Aug 26, 2009 4:22 pm) You continued to drive the vehicle with a blinking CEL. The manual specifically says not to drive with a blinking CEL because you may damage something (namely the catalytic converters). That's why it blinks. I think you're SOL.   That said, $3400 sounds awfully high. How much are the cats?
#17 of 20 Valve Guide Seals Leaking by iampattic Sep 23, 2009 (7:49 am)
I have a 2004 Lincoln LS 6 cyl with 32,000 miles on it. My engine light came on. I had codes read. PO304 is the code. Mechanic said that the "Valve Guide Seals are Leaking" and there is oil on the pistons. He isn't sure if he needs to remove the heads to repair this. Estimate is $1200.00. I need some help from someone! Would this be under any kind of warranty? Replies to this message: akirby (Sep 23, 2009 8:07 am) iampattic (Sep 23, 2009 10:43 am) akirby (Sep 23, 2009 11:57 am)

Replying to: iampattic (Sep 23, 2009 7:49 am) That's a misfire. It's usually caused by a COP failure. A valve guide seal problem would only affect air and fuel entering the engine. It would not cause oil to leak - that would be an oil ring problem with the piston or cylinder wall problem. I'd get a second opinion.

Replying to: akirby (Sep 23, 2009 8:07 am) The mechanic told me that this is the final cost. 6 hrs labor - 270 gasket sets (from Ford) - 220 Transmission - 50 Spark Plugs - 60 PCV - 8 Fuel Filter - 20 10 qts trans fluid - 42 oil change with Mobil 1 - 40 Total - 710   I told him to go ahead because I don't know what else to do.

Replying to: iampattic (Sep 23, 2009 10:43 am) He must have meant Valve Cover Gasket leak - huge difference. The valve cover gasket is leaking oil into the spark plug wells - common problem. The problem is the misfire is caused by a bad COP (which is caused by the oil leak). So you'll need to replace at least one COP if not several to fix the problem.
